Novak Djokovic admits he found it hard to swallow both losses he suffered at London 2012, and is surprised to have lifted a trophy so soon after the Games disappointment.

Djokovic lost in the semi-final to Andy Murray, the eventual gold medal winner, at the Olympics, then failed to snatch bronze as he was beaten by Juan Martin Del Potro in his next match.

However, he bounced back in some style with victory at the Rogers Cup on Sunday, brushing aside Richard Gasquet 6-3 6-2 for his first title in four months.

"It's a big tournament, one of the biggest we have in tennis. I'm very happy to be in this position," Djokovic said. "I truly did not expect myself to win this tournament after the emotional losses in the Olympic Games. I really took it hard. I tried to bounce back and recover; I've done great, I have to say."

Djokovic feels that the quality of his serving propelled him to victory in Canada. "I'm not one of the biggest servers in the game, that's for sure, but I always try to focus on the second shot after the serve," he said.

"I've been working on the efficiency of my first and second serve, but also trying to be aggressive in the first ball. It's been working exceptionally well throughout the whole week."
